Dental root-canal broach



FIG. 1 is an elevational view of a dental root-canal broach showing my new design;

FIG. 2 is a top plan view thereof; and

FIG. 3 is a bottom plan view thereof.

All elevational views of the new handle, not shown in the drawing, are similar to the view shown in FIG. 1 with two circumferential rows of knurls, and with a dome-shaped head. 

The ornamental design for a dental root-canal broach, substantially as shown and described.
